Dan Mahoney Books Overview

Detective First Grade

There’s a secret war on the streets of the city. Only a New York cop can win it. His claim to fame is finding guns on the bad guys, and Detective Second Grade Brian McKenna has just spotted the beard carrying a piece. What he doesn’t know is that he’s about to shoot his way into a war with a highly disciplined, well armed enemy so treacherous, not even the NYPD knows they exist. Exiled from the bright lights of Manhattan for breaking one too many rules, pressured by his girlfriend to quit the job, this is McKenna’s last chance to win back his reputation and make the coveted rank of Detective First Grade. But if his moves aren’t swift and right, a new breed of criminal who has found a leader in an exotically beautiful and ruthless woman will own his city. From the savvy and experience of a cop who gave over 25 years of his life to the NYPD comes a stunning novel of undeniable authenticity and unrelenting suspense.

The Edge Of The City

A terrorist stranglehold tightens on New York…
and only one cop can break its grip. Born in the mountainous jungles of Peru. Smuggled to the concrete jungles of NYC. It’s the most ingenious terrorist setup ever conceived, and it could bring the city and the nation to its knees. Former NYPD detective Brian McKenna has tangled with the Shining Path before. His new identity and early retirement in Florida were supposed to put him beyond the terrorist army’s retribution. But when the guerrillas cut down the son of his closest friend, New York’s police commissioner Ray Brunette, McKenna’s lured back into the center of the action, and into a deadly battle of wits with a brilliant man and a cunning and dangerous woman. Former NYPD Captain Dan Mahoney spins a chillingly authentic tale of a city held hostage, a city at the edge of disaster.


NYPD Detective Brian McKenna is back where he belongs hunting down a mysterious killer who preys upon the city’s most forgotten members. At first blush, it seems as if these homeless men have frozen to death on the city streets. But thsi succession of deaths seems too suspicious for McKenna to ignore. McKenna makes some curious findings: all the victims were HIV positive, and all were seen taking their last drink from a bottle of wine given them by a gaunt, black glad man who goes by the name ‘Hyde.’ Who is this sinister figure and why is he killing harmless men who are already at death’s door? A hell bent McKenna must chace the murderer from the streets of Manhattan through Europe and finally to Costa Rica to uncover the astounding answer. With first hand experience and masterful storytelling skills, former NYPD Capitan Dan Mahoney presents his most thrilling work to date.

Once In, Never Out

A girl missing in New York. A political bombing in Iceland. No ordinary cop would see a connection. But Detective First Grade Brian McKenna didn’t earn his reputation by being ordinary. In Once In, Never Out, McKenna travels the globe in pursuit of his darkest foe yet a terrorist bomber whose next target could be New York’s St. Patrick’s Day Parade. Along the way he finds a good friend and cunning ally in Thor Erikson, Iceland’s sole homicide detective. This is a case that brings McKenna to the edge of his abilities, and puts both his detecting and survival skills to the ultimate test.

Black and White

From the author of Once In, Never Out comes this gritty and explosive thriller featuring Detective First Grade Brian McKenna. When two New York City patrolmen come upon the savagely mutilated body of a young woman and the corpse of her male companion in Fort Tyron Park early one morning, they have no idea that their discovery will provoke a media frenzy. The murdered woman is Cindy Barone the daughter of a powerful member of the city council and the man she was with just before her death was not her husband. Detective First Grade Brian McKenna receives orders from the top to team up with a second of the force’s stars, first grader Tommy McKenna, and the murdered woman’s outraged family demands that the two find her killer, at whatever cost. With the press demanding explanations, the two McKennas embark on a hunt for a sad*istic criminal with a penchant for killing his victims slowly and violently. Their search takes them cross country where they penetrate the seamy underworld of illegal po*rnography. But as their manhunt intensifies, they learn that there might be two murderers, working together for a reason that only becomes clear with time. In Black and White, Dan Mahoney combines authentic procedural detail with relentless suspense and delivers his finest thriller to date.
